What makes our technology advanced?

Our shipping engine capabilities go far beyond what is available via either the native shipping capabilities of shopping carts such as WooCommerce or other shipping
services. While most shipping rate calculation services can sometimes adequately handle simple shipping situations for simple items, they quickly break down when
working with multiple items or quantities -- let alone any other complexities.

Advanced capabilities for managing USPS Flat Rate Boxes:

Ability to differentially select which flat rate box sizes you use

Configure the "percentage utilization" for fitting single and multiple items

Control whether a comparison is made between the cost of the flat rate box and the weight-based rate using your own box

Use the Regional Boxes if you qualify for Commercial Base rates

Use Cubic pricing if you qualify for Commercial Plus rates

Determine the best price between standard flat rate, regional boxes, and cubic rates
